HOLLOW INTER/BONDING BRICK AND CONSTRUCTION.

To all whom izfmag concern:

Be it known that 1, JAMES JFUNSTEN, a

' citizen of the UnitedStates, residing at San My invention relates toan interbonding hollow building brick and structures com-.

posed of such brick, and to a'means of uniting such brick so as ,toimakea strong integral structure. It also enables the brick to be laid in thewall so that the structure is completed with one given width and form ofbrick in a single continuous operation.

It further consists in a novel construction of grooved brick, which areshaped to engage with each other in positions so related that with asuitable cement they may be united to form strong integral structures.

The invention includes details of construction, which will be more fullyexplained by reference to the accompanying drawings in which,

Figure 1 is a perspective view of a brick constructed in accordance withthe present invention r Fig. 2 is a similar view of a modified form ofbrick embodied in a wall construction: and

Figs. 3 and 4: are perspective views of walls constructed with the typeof brick depicted in Fig. l.

As shown in the drawings, A represents the face and back of the brick; Brepresents the interior walls of the tile; C represents the bottom wallsof thebrick and D represents the top wall of the brick.

'The cement receiving channels are represented by the number 1.Thehollow channels are represented by the number 2. The block, in itssimplest form, therefore, comprises spaced U-shaped members arrangedside by side and having their inner arms con- 'nected at their upperedges by a bridge.

Fig. 1 shows the construction of the brick.

Fig. 2 shows additional air and cement receiving channels when desiredfor additional width and strength.

Fig. 3 is a perspective view showing these bricks superposed and showshow the walls A are placed one over the other in different courses toform the face and back of the Specification of Letters Patent.

wall. The walls B also are placed in vertical alinement. The wall Dwhich forms the top of the brick and connects the cement receivingchannels, number 1, prevents the 'mortar or other material from runninginto and. closing the hollow channels number 2;

Fig. 8 shows how the cement receiving channels number lare placed oneupon the other in diiferent courses, and separated by the bottom'wall C.

In structures consisting of walls or their equivalents and supplementalsurfacing, va-

rious methods have been employed to secure such structuralelements-together. In this invention, I unite and combine all structuraland facing units for any given thickness of wall. into one brick withoutthe use of connecting rods or other extraneous means.

This brick maybe made of any suitable material, and when manufactured ofclay it will be obvious that any variety may be used to produce anydesired color, texture or finish. corrugated, plain or roughened to givea rustic effect to the finished wall. The surfaces of the brick may bescored wherever desired for the better bonding of the mortar or adhesionof the plaster, which when used may be applied directly to the surfaceof the brick without the necessity for the use of furring orwaterproofing.

While not limiting this brick to size, it will be obvious that in widthit will be made to conform to the accepted requirements of giventhickness for walls, and of such a height and length as to conform tothe usual and accepted building brick sizes and proportions in heightand length, as in the completed wall they will have the same appearance.

These brick when laid in the wall are much stronger for relative weightin resisting all strains that may be applied than usual brickconstruction, due to their shape The face may be vitrified, glazed,

The brick are shown as hollow for lightness and formed with a minimum ofmaterial required to obtain necessary strength, Great strength andrigidity are obtained by the manner in Whichthe brick are-used The sizemay be so governed that any desired thlckness of wall may be combined;in. one,

My brick may be manufactured, due to,

their simplicity of design and, lightnessof weight, very economically,alsodue to their size, shape, light weight. and the manner in which theyare laid, thelabor cost of. constructing is reduced.

The brick are preferably so laid withreference to each other that eachoverlap, thus breakingallvertical joints and permitting any bond orpattern work to be employed.

Having thus described my invention, what I claim and-desire to secure byLetters. Patent is,

1. A hollow tile brick comprising, in its Copies of this patent may beobtained for entirety, similar spaced U-shaped' members of uniform withand depth arranged side by side, and; a Ueshaped bridge havingilateral owings integrally connecting the adjacent inner walls of-the U-shapedmembers at their upper edges to provide a pair of similar downwardlyfacing spaces, the thickness of the Walls. of the u-shaped members andbridge being uniform throughout. I

2. A hollow tile brick comprising, in its entirety similar spacedUshaped members of uniform width and deptharranged side by side andconstituting twinwalled mortar receiving channelsof substantial width,and a horizontal bridge integrally connecting the adjacent inner wallsof the U-shaped members at theirnpper edges to providea downwardlyfacing; channel, forming-an air space, the thickness of the walls of theU- shaped members and bridge being uniform throughout,

In testimony whereof, I hereuntoaflix my signature in the presence oftwo witnesses.
